EMBODIMENTS OF THE PRESENT DISCLOSURE

The solutions of the embodiments of the present disclosure are clearlyand completely described below with reference to the accompanyingdrawings in the embodiments of the present disclosure. Obviously, thedescribed embodiments are merely part of rather than all of theembodiments of the present disclosure. All other embodiments obtained bypersons of ordinary skill in the art based on the embodiments of thepresent disclosure without making creative efforts shall fall within theprotection scope of the present disclosure.

A charging indication method provided by embodiments of the presentdisclosure is applied in a terminal. The terminal includes a smartphone,a tablet computer, a smart wearable device, a digital audio and videoplayer, an electronic reader, a hand-held game console, avehicle-mounted electronic device or other electronic devices.

FIG. 1 is a flow chart of a charging indication method according to anembodiment of the present disclosure. The method is applied in aterminal including a flexible display screen and a battery. Asillustrated in FIG. 1, the method includes followings.

At block S101, in response to detecting that the terminal is in acharging state, a current ratio of remaining battery capacity to totalbattery capacity is acquired.

In detail, the terminal detects whether the terminal is in the chargingstate. When the terminal is in the charging state, the current ratio ofthe remaining battery capacity to the total battery capacity isacquired. When the terminal is not in the charging state, no furtherprocessing is required. For example, assuming that the remaining batterycapacity is 2000 mAh and the total battery capacity is 2500 mAh, thecurrent ratio is 80% (=2000/2500).

In an implementation, the terminal may detect whether the battery is inthe charging state through a power management system, or may detect theremaining battery capacity through the power management system tocalculate the current ratio of the remaining battery capacity to thetotal battery capacity.

In an embodiment, the terminal may be charged by coupling to a powerwire, or by coupling to a charging socket, which is not limited herein.Preferably, the terminal is charged by coupling to the charging socket,and the jack of the charging socket go upwards such that the terminalmay be located vertically, as illustrated in FIG. 5, which is convenientfor the user to check a shape change.

At block S102, a target curvature angle of the flexible display screenis determined based at least on the current ratio.

Alternately, before block S102, the terminal determines whether thecurrent ratio is greater than a predetermined ratio threshold, if yes,an act at block S103 is executed, otherwise, an act at block S101 isexecuted. The predetermined ratio threshold may be configured by amanufacturer of the terminal before the terminal comes onto the market,or may be configured by the user in advance, which is not limitedherein. For example, the predetermined ratio threshold can be set to be2%. In some embodiments, the purpose of determining whether the currentratio is greater than the predetermined ratio threshold is in that, apower consumption is caused by a curvature of the terminal, when theremaining battery capacity is low, the curvature of the terminal maycause the battery to discharge overly or cause the terminal to be shutdown.

In detail, the terminal determines the target curvature angle of theflexible display screen based at least on the current ratio. When thecurvature of the flexible display screen occurs, the curvature angle ofthe flexible display screen can be calculated in many ways. Thecurvature angle of the flexible display screen may be an angle between atangent plane at the maximum curvature of the flexible display screenand a predetermined reference plane (the predetermined reference planemay be a horizontal plane or a reference plane perpendicular to thehorizontal plane). When the terminal is charged via the charging socket,the curvature angle of the flexible display screen may be an anglebetween a line connecting two ends of the terminal and a lineperpendicular to a surface of the charging socket, or may be an anglebetween the line connecting two ends of the terminal and a line parallelto the surface of the charging socket. The curvature angle of theflexible display screen may be an angle between the line connecting twoends of the terminal and a predetermined reference plane or apredetermined reference line (the predetermined reference line may be aline in a tangent plane of one end of the terminal). For example, thecurvature angle may be an angle between a line connecting two ends ofthe terminal and a tangent line at one end, as illustrated in FIG. 7,the curvature angle is the angle between a line connecting points A andB and a tangent line at point A. The bigger the curvature angle is, thehigher the curvature of the terminal is.

Alternatively, the terminal stores a pre-established correspondencebetween ratios and curvature angles, such that the terminal may querythe target curvature angle corresponding to the current ratio accordingto the correspondence. For example, assuming that the current ratio is10% and the curvature angle corresponding to the ratio of 10% in thecorrespondence is 30°, the terminal may query the target curvature angleof 30°.

In an embodiment, the ratio may be in inverse proportion to or inproportion to the curvature angle in the correspondence, which is notlimited herein. Preferably, the ratio is in inverse proportion to thecurvature angle in the correspondence, such that the higher the ratiois, the smaller the curvature angle is. Further, in the correspondence,the curvature angle of 0° has a corresponding ratio of 1. The curvatureangle of 0° means that there is no curvature. When the battery is fullycharged, the terminal is straight, as illustrated in FIG. 6.

At block S103, the flexible display screen is controlled to present thetarget curvature angle, so as to indicate a charging progress throughthe target curvature angle.

For example, during a process of the current ratio changing from 0% to100%, the curvature angle of the flexible display screen changes from45° to 0°. In other words, the terminal becomes straight from a bentstate. The user may acquire the charging progress from the curvatureangle of the terminal.

Alternatively, the flexible display screen of the terminal may beprovided a plurality of electromagnets arranged side by side at thebackside, as illustrated in FIG. 8. The electromagnet may be in a formof prismatic table. The terminal may control a polarity of an electrodeand a magnetic intensity of each electromagnet, so as to control theattractive force and/or repulsive force between the electromagnets.Accordingly, the terminal may control the flexible display screen topresent the target curvature angle by controlling the polarities ofelectrodes and/or magnetic intensities of the plurality ofelectromagnets. For example, when the south magnetic pole and the northmagnetic pole present alternately in the plurality of electromagnets, asillustrated in FIG. 9, the attractive force between the electromagnetscan be controlled by controlling the magnetic intensity of eachelectromagnet, such that the degree of curl of each electromagnet can becontrolled, further the curvature degree of the terminal can becontrolled.

The terminal including the flexible display screen and the batteryaccording to the embodiments of the present disclosure may acquire thecurrent ratio of the remaining battery capacity to the total batterycapacity in response to detecting that the terminal is in the chargingstate, determines the target curvature angle of the flexible displayscreen based at least on the current ratio and controls the flexibledisplay screen to present the target curvature angle so as to indicatethe charging progress through the target curvature angle. In this way,the user may acquire the charging progress conveniently and intuitively.

FIG. 2 is a flow chart of a charging indication method according toanother embodiment of the present disclosure. The method is applied in aterminal including a flexible display screen and a battery. Asillustrated in FIG. 2, the method includes followings.

At block S201, it is detected whether the terminal is in a chargingstate.

In detail, the terminal detects whether the terminal is in the chargingstate, if yes, an act at block S202 is executed, otherwise, no furtherprocessing is required.

In an embodiment, the terminal may be charged by coupling to a powerwire, or by coupling to a charging socket, which is not limited herein.Preferably, the terminal is charged by coupling to the charging socket,and the jack of the charging socket go upwards such that the terminalmay be located vertically, as illustrated in FIG. 5, which is convenientfor the user to check a shape change.

At block S202, a current ratio of remaining battery capacity to totalbattery capacity is acquired.

In detail, the terminal detects the remaining battery capacity through apower management system to calculate the current ratio of the remainingbattery capacity to the total battery capacity. For example, assumingthat the remaining battery capacity is 2000 mAh and the total batterycapacity is 2500 mAh, the current ratio is 80% (=2000/2500). In animplementation, the terminal may detect whether the battery is in thecharging state through the power management system.

At block S203, it is determined whether the current ratio is greaterthan a predetermined ratio threshold.

In detail, the terminal determines whether the current ratio is greaterthan the predetermined ratio threshold, if yes, an act at block S204 isexecuted, otherwise, an act at block S202 is executed. The predeterminedratio threshold may be configured by a manufacturer of the terminalbefore the terminal comes onto the market, or may be configured by theuser in advance, which is not limited herein. For example, thepredetermined ratio threshold can be set to be 2%.

In some embodiments, the purpose of determining whether the currentratio is greater than the predetermined ratio threshold is in that, apower consumption is caused by a curvature of the terminal, when theremaining battery capacity is low, the curvature of the terminal maycause the battery to discharge overly or cause the terminal to be shutdown.

At block S204, a target curvature angle of the flexible display screenis determined based at least on the current ratio.

In detail, the terminal determines the target curvature angle of theflexible display screen based at least on the current ratio. Thecurvature angle may be an angle between a line connecting two ends ofthe terminal and a tangent line at one end, as illustrated in FIG. 7,the curvature angle is the angle between a line connecting points A andB and a tangent line at point A. The bigger the curvature angle is, thehigher the curvature of the terminal is.

Alternatively, the terminal stores a pre-established correspondencebetween ratios and curvature angles, such that the terminal may querythe target curvature angle corresponding to the current ratio accordingto the correspondence. For example, assuming that the current ratio is10% and the curvature angle corresponding to the ratio of 10% in thecorrespondence is 30°, the terminal may query the target curvature angleof 30°.

In an embodiment, the ratio may be in inverse proportion to or inproportion to the curvature angle in the correspondence, which is notlimited herein. Preferably, the ratio is in inverse proportion to thecurvature angle in the correspondence, such that the higher the ratiois, the smaller the curvature angle is. Further, in the correspondence,the curvature angle of 0° has a corresponding ratio of 1. The curvatureangle of 0° means that there is no curvature. When the battery is fullycharged, the terminal is straight, as illustrated in FIG. 6.

At block S205, the flexible display screen is controlled to present thetarget curvature angle, so as to indicate a charging progress throughthe target curvature angle.

For example, during a process of the current ratio changing from 0% to100%, the curvature angle of the flexible display screen changes from45° to 0°. In other words, the terminal becomes straight from a bentstate. The user may acquire the charging progress from the curvatureangle of the terminal.

Alternatively, the flexible display screen of the terminal may beprovided a plurality of electromagnets arranged side by side at thebackside, as illustrated in FIG. 8. The electromagnet may be in a formof prismatic table. The terminal may control a polarity of an electrodeand a magnetic intensity of each electromagnet, so as to control theattractive force and/or repulsive force between the electromagnets.Accordingly, the terminal may control the flexible display screen topresent the target curvature angle by controlling the polarities ofelectrodes and/or magnetic intensities of the plurality ofelectromagnets. For example, when the south magnetic pole and the northmagnetic pole present alternately in the plurality of electromagnets, asillustrated in FIG. 9, the attractive force between the electromagnetscan be controlled by controlling the magnetic intensity of eachelectromagnet, such that the degree of curl of each electromagnet can becontrolled, further the curvature degree of the terminal can becontrolled.

At block S206, it is determined whether the current ratio is 100%.

In detail, the terminal determines whether the current ratio is 100%, ifyes, an act at block S207 is executed, otherwise, an act at block S202is executed.

At block S207, the terminal is not charged and a charging indicationlight is turned off.

In an embodiment, the charging of the terminal is stopped, such thatovercharging of the terminal can be avoided. Additionally, in therelated art, during the charging process of the terminal, when thecharging indication light illuminates red light or yellow light, itindicates that the terminal is charged. When the charging indicationlight illuminates green light, it indicates that the charging iscompleted. However, in the present disclosure, the user may determinewhether the charging is completed according to the shape change of theterminal, for example, when the terminal is straight, it indicates thatthe charging is completed, such that it is unnecessary to utilize thecharging indication light to indicate whether the charging is completed,and the power consumption caused by the charging indication light can beavoided by turning off the charging indication light.

The terminal including the flexible display screen and the batteryaccording to the embodiments of the present disclosure may acquire thecurrent ratio of the remaining battery capacity to the total batterycapacity in response to detecting that the terminal is in the chargingstate, determines the target curvature angle of the flexible displayscreen based at least on the current ratio and controls the flexibledisplay screen to present the target curvature angle so as to indicatethe charging progress through the target curvature angle.
